5 Claims. (Cl. 56377) The invention relates to a rake with a row of rakewheels for laterally displacing material lying on the ground.

It is an object of the invention to provide an improved implement whichcan be towed by a tractor.

In accordance with the invention, a raking attachment, for combinationwith a tractor having a power lift mechanism including a pair oftransversely spaced vertically swingable links, comprises a frame havingfreely rotatable raking members mounted in echelon thereon for sidedelivery, connecting means provided at transversely spaced points on theframe for p-ivotally attaching it to the links to allow its freemovement'in a vertical plane and serving also to prevent its movement ina lateral direction relative to the direction of travel of the tractor.The raking attachment includes ground engaging means for supporting theframe in an operative position above the ground. The connecting meansfor attachment to the tractor provides for preventing lateral movementof the frame. The frame comprises essentially an elongated frame beamwith the connecting means at one end and supporting arms on which saidraking members are mounted attached thereto.

This is a division of our application Serial No. 549,482, to issue asPatent No. 2,933,878, on April 26, 1960.

In order that the invention may be clearly understood and readilycarried into effect, reference will now be made, by way of example, tothe accompanying draw ings, wherein:

FIGURE 1 is a plan view of an implement attached to the power lift of atractor and FIGURE 2 shows a side elevation of a modified detail of theimplement in FIGURE 1 viewed in the direction of the arrow II.

Referring to FIGURE 1, a tractor 60 carries a threepoint lifting device66A having three link ends 61, 62 and 63. Link end 63 is located at ahigher level than link ends 61 and 62. Disposed between link ends 61 and62 is an angle-section bar 68 carrying an axle 64A having ends 64 and 65which bear pins 61A and 62A which comprise the connecting means adaptedto pivot in link ends 61 and 62. Two supporting bars 66 and 67 extendingobliquely upwards are hinged at their upper extremities to link end 63and at their lower extremities to angle-section bar 68.

Angle-section bar 68 is connected to one end 69 of a tubular frame beam70, the connection being reinforced by an interconnecting bar 71extending substantially in the intended direction of travel of thedevice. Chain 72 connects link end 63 to a hook 73 on beam 76, and thuslimits downward movement of the implement relative to the tractor aboutthe axis of the axle 64A. Two-part sleeves 74, 74A, 74B, 74C, 75 and 75Aare clamped on the beam 70. Sleeves 74, 74A, 74B and 74C are spaced anequal distance apart. The distances between the sleeves can, however, bealtered as desired by simply releasing and re-clamping the sleeves indifferent positions. Any ordinary clamping and releasing meansappropriate to the purpose may be employed.

Sleeves 74, 74A, 74B, 74C, and 75A carry short arms 76, 76A, 76B, 76C,77 and 77A which (except for arms 77 and 77A) extend away from thetractor. These arms are parallel, and each has disposed on its end aconnection 76 having a pivot 79. Each connection can be secured in anyone of a plurality of positions by the introduction of a pin 86 into anyone of a number of holes 81.

Axles 82, 82A, 82B, 82C, 83 and 83A are mounted on each connection 78and angular movement of the axles relative to their respective arms 76,76A, 76B, 76C, 77 and 77A are prevented by the corresponding pin 86,disposed in one of holes 81. Rake wheels 84, 84A, 84B and 84C arerotatably mounted on axles 82, 82A, 82B and 82C, and supporting devicesincluding ground wheels 93 and 93A are attached to the extremities ofaxles 82C and 82A. Rake wheels 84, 84A, 84B and 840 are arranged in asingle row extending along and behind the frame beam 76, the relativearrangement of the rake wheels being such that in use they cooperate andthe implement acts as a side-delivery rake. Each rake wheel will, duringthe use of the implement, be disposed obliquely to the line of traveland will be rotated by co-action with the ground or the crop lyingthereon, or both.

Sleeves 75 and 75A carry two rake wheel supports 83 intended to permitconversion of the side-delivery rake to a swath turner as set forth inmore detail in the parent application, Serial No. 549,482. Betweensleeves 75 and 75A, beam 76 has secured to it means 100 for theconnection thereof to the lifting device 66A of the tractor, to servethe same purpose as the connecting means constituted by the previouslydescribed elements 61, 61A, 62, 62A, 64, 64A, 65, 66, 67A and 68. Theadditional connecting means 166 permits the implement to be brought toanother working position as set forth in more detail in the parentapplication, Serial No. 549,482. Thus a beam 89 which carries pins 90and 91 at its ends is mounted on bar 88 which is supported by two shortstruts 85 and 86. Two short arms, 92 and 92A, are mounted on beam 70near struts 86 and 85. When the rake is turned upside down, pins 90 and91 can be hingedly connected to ends 62 and 61 and arms 92 and 92A cansimilarly be connected to end 63 whereby the implement becomes a tedder.

As disclosed in the parent application, instead of the implement runningon shoes it may run upon wheels 93 and 93A as shown in the figuresherein. Wheels 93 and 93A have horizontal axles 151 and 151A which areconnected by means of oblique bars 152 and 152A to bushings 153 and 153Awhich are rotatable about vertical pins 154 and 154A. Pins 154 and 154Aare attached to further bushings 155 and 155A which can rotate about theaxles 82A and 82C but which can be secured against such rotation by pins156 and 156A.

The above description and drawings disclose several embodiments of theinvention, and specific language has been employed in describing theseveral figures. It will, nevertheless, be understood that nolimitations of the scope of the invention are thereby contemplated, andthat various alterations and modifications may be made such as wouldoccur to one skilled in the art to which the invention relates.
